In substitution reaction between bromine and hexane, why the bromine should be in organic solvent? Bromine is already a liquid!
A substitution reaction in organic chemistry is a type of chemical reaction in which an atom or group of atoms in a molecule is replaced by another atom or group of atoms. This process involves breaking a bond between two atoms and forming a new bond with a different atom or group.
There are two main types of substitution reactions in organic chemistry: nucleophilic substitution and electrophilic substitution. In nucleophilic substitution, a nucleophile (electron-rich species) replaces a leaving group from a molecule. In electrophilic substitution, an electrophile (electron-poor species) replaces a hydrogen atom in a molecule.
The rate of a substitution reaction is influenced by several factors, including the nature of the substituents, the strength of the bonds being broken and formed, and the type of reaction mechanism. Other factors such as temperature, solvent, and concentration can also affect the reaction rate.
A substitution reaction involves replacing an atom or group of atoms in a molecule, while an addition reaction involves adding new atoms or groups of atoms to a molecule. Additionally, substitution reactions typically result in a change in functional groups, while addition reactions do not necessarily change the functional groups of the reactants.
Substitution reactions are common in everyday life, such as the reaction between chlorine and sodium to form table salt (sodium chloride). Other examples include the breakdown of food in our bodies, the synthesis of medications, and the production of plastics from petrochemicals.
